R-Phycoerythrin or R-PE is a fluorescent probe belonging to the group of phycobiliproteins obtained from macroalgae. R-Phycoerythrin (R-PE) is a protein acting as a photosynthetic accessory pigment in red algae (Rhodophyta). It is an oligomeric protein of 240 kDa, with 6 α (about 20 kDa), 6 β (about 20 kDa), and 1 γ (about 30 kDa) subunits. Phycobiliproteins are water-soluble light-harvesting proteins with a high fluorescent property.
Application
R-Phycoerythrin (R-PE) is useful in the laboratory as a fluorescence-based indicator for the presence of cyanobacteria and a variety of immunofluorescence applications. R-PE is a useful fluoroprobe in various electrophoretic procedures. R-Phycoerythrin (R-PE) proteins detect mercury ions in soil and groundwater samples. Phycoerythrin has been widely used in food, cosmetics, immunodiagnostics, and analytical reagents.
Analysis Note
The product is suspended in 150 mM sodium phosphate, 60% ammonium sulfate, 1 mM EDTA, 1 mM sodium azide, pH 7.0 and must be dialyzed against conjugation buffer or PBS before conjugation.A566/A280 >4.6, A620/A566 <0.03, A566/A498 <1.5

R-Phycoerythrin (R-PE) is a protein acting as a photosynthetic accessory pigment in red algae (Rodophyta). This protein has gained importance in many biotechnological applications in food science, immunodiagnostic, therapy, cosmetics, protein and cell labelling, and analytical processes. In this paper
Mercury, as one of the most prevalent toxic metals released by various natural and anthropogenic processes, causes severe pollution of soil and groundwater. In this work, R-phycoerythrin (R-PE) proteins encapsulated into ZIF-8 composite thin films were prepared via a solid-confinement

We present a formalism to quantify the contribution of path-interference in phonon-mediated electronic energy transfer. The transfer rate between two molecules is computed by considering the quantum mechanical amplitudes associated with pathways connecting the initial and final sites. This includes

The red/far-red light photoreceptor phytochrome mediates photomorphological responses in plants. For light sensing and signaling, phytochromes need to associate with open-chain tetrapyrrole molecules as the chromophore. Biosynthesis of tetrapyrrole chromophores requires members of ferredoxin-dependent bilin reductases (FDBRs). It was shown
